Be it known that 1', CARL SoHUsTEn, a citizen of the United States, residing at Bellevue, in the county of Allegheny and "State of Pennsylvania, have invented certain new and useful Improvements in Con- ":iductor-Posts of which the following is a specification. I

fiat conductor bars and intervening similar I My invention relates to improvements in conductor posts for knife switchesand similar electrical apparatus, and it has for its object to provide a post of this class composed of a plurality of comparatively thin spacers, fixedly connected together and provided with, or adapted to be provided with g i' insulating base. 39"

such parts may be handled andshipped as a unit independently of said frame." They also positively hold the bars "ind spacers against spreading or edgewis'e movement within the base. Also, whereby an embracing frame is fixedly connected withtheem tire construction so as to provide a'nnitary structure WhICll is easily adapted to innerporation with the other elements- 0f the equipment.

The construction of the post, as r greatly contributes to and facilitates the operation of assembling the parts; In the drawings, 2 is the insulatinglmse of a switch board or other shnilar construction, through which the crxnposite post tends, two such posts being usually employed whereby to provide terminals at one side of the. base for connection with the bus bar terminals 3, 4, and at the other side forthe connecting switch blades 5, of well. known,

of the base 2, and the endsi lof the switch, blades 5 at the other side of the base; For

the purpose of so spacing the bars 6, Tier! ploy aseries of fiat spacers 7. These may v be of a length and so located as tocorrespond substantially to the combined thiekness of the base 2 and the holding frameS," or of greater or-shorter length as desired, provided there is enough stock to provide for the holding rivets. These spacersjare similar to the conductors in every respect, but shorter, and 813 shown, may beof vary ing thickness to provide the desired "space between each member ofeach pair of conductors, corresponding to the thickness of the bus bar strips and switch blades, and of a slightly less width for separation of one pair of conductors from the next avd a-cent pair. The spacers are of the same-width asthe'conductors and are flat and comparativelythin, and when the conductors and fspacers are assembled, they fit tightly and compactly together.

In assembling the several conductors and spacers, thelatter are interleaved and locomposed of a series' ofeoxf cated at the proper distance longitudinally of thecon'di'ict'ors, and the combined 'structure is then clamped together byclamp's en ing spacers,

gaging the sides of the ,outer conductors for Fig 5., By this means, due to the interventhe assembled conductors and spacers are rigidly held immovably. in-the clamp, and rivets 9 are thenpassed through themselves.
